Category: Failure Predictions

A quick review of Linear Elastic Fracture Mechanics (LEFM), and how it applies to thermoplastics and other polymers.

Article about creep rupture behavior of different thermoplastics, and how you can predict creep rupture in a FE simulation.

Article presenting the Christensen’s failure theory for materials under monotonic loading. The theory is compared to UHMWPE data.

You can predict failure of thermoplastics under monotonic loading using a strain-based failure condition with triaxiality dependence.

Tutorial showing how to calibrate a PolyUMod TNV stress-strain and failure model to experimental data.

A case study aimed at showing how to use the different cohesive elements and surface models available in Abaqus.
